Abstract

L'invention concerne un système de haut-parleur portatif qui réalise une forte présence grâce à la reproduction de basses. Le système de haut-parleur portatif est équipé d'une enceinte (101). Une première unité de haut-parleur (102L) et une première partie d'ouverture (104L), laquelle est une extrémité d'un premier conduit bass-reflex, sont disposés dans une première région d'extrémité de l'enceinte (101). Une seconde unité de haut-parleur (102R) et une seconde partie d'ouverture (104R), laquelle est une extrémité d'un second conduit bass-reflex, sont disposés dans une seconde région d'extrémité de l'enceinte (101). Les première et seconde unités de haut-parleur (102L, 102R) ont chacune un haut-parleur (103) et un radiateur passif (105) qui est orienté dans la direction opposée au haut-parleur (103). L'espace entre le haut-parleur (103) et le radiateur passif (105) dans chacune des première et seconde unités de haut-parleur (102L, 102R) est connecté à un espace à l'intérieur de l'enceinte (101).
